The home ADR 0050 left open for a usage reading. mesh-control is a CLI and
cannot consume events, so the store that keeps the current usage picture is a
MODULE — the audit-logger's sibling: it consumes `module.*.usage.*` and upserts
each reading into its own provisioned postgres store, latest per
(licence, consumer, period, metric), in the clear. One vendor-neutral table
holds BOTH grains; they differ only in `consumer` (the holding module for the
licence grain, the session for the finer one). The consumer creates its table
on startup and, as a restart-until-ready service, self-heals rather than
gating the apply on a run-once that must reach a provider over the overlay.
The vendor->row normalisation moves into the adapter, as ADR 0054 requires:
anthropic-manager (licence grain, utilization%) and anthropic-consumer (session
grain, token/cost) now emit already-normalised { rows: UsageRow[], raw } on
their existing keys, so the store stays vendor-blind.
Proven end to end by the mesh-lab model-usage bed (green): a usage event
emitted into the mesh is upserted at both grains, latest-per-key, in the clear.
